Well, it seems the back and forth of N54 tuning horsepower records is over... for now. Earlier this month Vargas Turbo Tech and Pro Tuning Freaks (with a Cobb flash) set the N54 hosrepower record at 693 wheel horsepower. That basically obliterated what anyone else had hit on this platform. A competing tuner with a single turbo (the Vargas VTX63 upgrade consists of twin turbos) N54 upgrade kit out of nowhere pulled out suspect numbers that eeked out a few more wheel horsepower.

This became an ego pissing match of sorts but Vargas and Pro Tuning Freaks went back to the dyno to make some adjustments and managed to surprisingly quickly and easily take the horsepower record right back (and where it rightfully belongs due to the breakthrough being thanks to the Vargas work with the High Pressure Fuel Pump) with a 725 wheel horsepower pull.

A video is included below along with two graphs. The E92 335i is equipped with a Pro Tuning Freaks pro tuning using the Cobb flash system, 109 octane race gas, meth injection, and of course the Vargas Turbo Technologies VTX-R 63 (GTX2863R) twin turbo upgrade and HPFP upgrade.

Congratulations to Vargas, PTF, and Cobb for pushing the platform into new territory.

Nah, it serves only to give Shiv yet another venue to propagate his bull$#@!. If I were Tony I'd just ignore Shiv all together, get these kits in the hands of his tuners (Dzenno, myself, Jake, and whomever else will be tuning them), and let us show Shiv and his customers what the hardware is really capable of.

Like I was telling Tony, Just wait till Terry and Dzenno gets a hold of the kit, then we will really see what it is capable of.
Kits coming off this week for production. Can't wait to see your numbers Terry.

Nice numbers guys. Can't wait to see the 60 - 130 times. Should be sick. BTW, did you ever replace the DMF for a SMF or did you just disable sensors to keep the car from coding? I know this was an issue with some of the RB and ST cars, just wondering.

If if and i would like to make a point IF Shivs 700whp dyno is real it will beat the current vargas setup

Uh no, it won't. The Vargas setup makes more power under the curve over the rpm span that covers gear changes. The only time the Vishnu setup makes more power is in the early part of the rpm band that never gets touched except at launch. And even then, the sharp torque increase vs the broad increase of the Vargas setup will be much harder to control and induce more wheelspin.

I was thinking the same thing. For the 60-120 race...I would think it wouldn't matter because the car would be in hgher revs....as for the 1/4 mile...wouldn't the lower torque lend to better traction and as the torque/hp went up the car would just accelerate faster with less chance os wheel spin?

This single curve was produced at less boost which comes on earlier for similar mass flow potential. Still too early to choose for me, as I do like the twin setup... but single is looking better so far.

For the sharp torque curve this is what you want. You can always modulate the throttle for control.

BMW tortured the hell out of the N54 motor to find its max potential and then rolled it back.

I would say 800+ hp before something breaks which will start with lack of fuel if they are going to use the stock fuel pumps.

I know its a completely different engine, but the pics ive seen of the N54s bottom end/recipricating assembly looks very similar to the LS series.

When you are done starting a zombie up rising here are some 800+ hp BMW engines that have been "totured" to there "max potential" ! Enjoy:thumbsup: http://www.usautoparts.net/bmw/engines/racing.htm

So all those people who thought I was talking out my a$$ about the N54 making it to 800hp...well....you can now kiss my

Are we still comparing boost between the two completely different turbo setups And there's nothing attractive about the single because it still doesn't work 100%. It also took a forced revision after ~1 full year of being on sale for Shiv to offer the 6466 turbo option, otherwise the Vargas Stage 3 (and remember this isn't the Top Tier Kit) would've walked right on by unchallenged.
